BAYLOAM323A TCC - F TCX - F TCY - F YCC - F YCX- F YCY- F WCC - F WCX - F WCY - F Head Pressure Control (208/230V/460V) NOTE: As the head pressure control is applied to units operating at low ambient conditions, it is necessary that these units have compressor crankcase heat. If the unit does not have a factory provided crankcase heater, than field installation of the crankcase heater kit BAYCCHTOO3A is required. iNSTALLATiON forTC*/YC*/WC*048=060F units NOTE: The controller is factory calibrated for operation on the TC*/YC*/WC*O48F and =060F units. No additional calibration is required. DUE TO ELECTRICAL SHOCK OR CONTACT WITH MOVING PARTS. LOCK UNIT DISCONNECT SWITCH IN OPEN POSITION BEFORE SERVICING UNIT. I WARNING: lap it over the sensor, as you wrap to insure a firm contact between the metal tab on the sensor and the liquid line. 7. After the controller is wired and BEFORE applying power, with an ohmmeter measure the resistance value between load (#1) terminal on the controller and the CC-1 side of the contactor( RED wire). Five ohms or greater should be obselwed. DO NOT apply power until you review the wiring diagram, and correct the wiring errors. NOTE: If installed on WC*-F heat pump units, the relay (BAYRLAYOO5A) MUST be disconnected in order to get a proper reading. INSTALLATION forTC*/YC*/WC*018=042F UNITS TOPREVENT INJURY ORDEATH NOTE: 1. Remove the control box access panel. 2. Remove the heater section access panel. 3. See figures 1 or 2 for mounting the head pressure control inside of the heater/furnace compartment. 4. Feed the high and tow voltage electrical wires through the top opening in the side of the electrical control box. See Figures 1 or 2. Connect the electrical wires to the controller and also make the electrical connections in the unit control box per the wiring diagram in Figure 4. The black motor lead must be moved from the CC-2 contactor and connected with the line connector to the BLACK wire (from kit with ferrite inductor) to the load (#1) terminal on the controller. Attach the BLUE wire (from kit) to the same CC-2 contactor (where the black motor lead was attached) and to the line (#2) terminal on the controller. Attach the RD and the BL (18 ga) low voltage leads to the 24V source (YC* use R and B on the ignitor board) (TC*/WC* use RD and BL thermostat leads. 5. Feed the sensor wires through the top opening on the condenser side into the condenser section. See Figures 1 or 2. Connect the sensor wires to the controller per the wiring diagram in Figure 4. 6. Mount the sensor to the liquid line as close to the condenser coil as posibite (see Figure 3). Use all of the special tape provided to secure the sensor to the liquid line. Stretch the tape slightly, and © American Standard Inc. 1998 The 1/5 H.R 230 V outdoor fan motor in the the following units must be replaced with the BAYMOTR3OTA 1/2 H. R 230 V outdoor fan motor.

CONTROL OPERATING If the liquid line temperature CHARACTERISTICS is: 1. Below 50°F, condenser fan will not start. 2. At 53°F, motor will start at full speed and full voltage for 5 seconds and reduce to minimum speed. 3, Between 53°F and 78°F liquid line temperature the condenser fan motor will start at full speed and full voltage for 5 seconds and then reduce down to a speed proportional to the liquid line temperature. 4. Between 78 °F and 80 °F liquid line temperature, the motor speed changes from approx. 90% of full rpm to full synchronous rpm. 5. Above 80°F liquid line temperature, the condenser fan motor remains at full synchronous rpm and the controller switches directly to line voltage. INSTALLER'S CONTROLLER GUIDE CHECKOUT=- SENSOR a. With the unit operating, check that the fan motor is running, remove power to the unit and remove one of the sensor leadsrepower the unit and the fan motor should not run. If the motor starts the controller is bad CHECKOUT== If the fan motor does not change speed below an outdoor ambient of 80°F, and the controller has been checked out per the procedures in sections A and B, check the sensor contact with the liquid line. If proper sensor contact is made, check the resistance value of the sensor per the values in the Sensor Resistance Table. b. Remove power to the unit and remove the second sensor lead and jumper (short) the sensor terminals, repower the unit and the motor should start and operate at max rpm. Sensor c. Remove power and replace the sensor leads to the correct teminals. Resistance Table Temperature (° F) d. Measure the voltage across the line and load terminals, place the sensor in ice water-the motor should stop. e. Remove the sensor and warm in your hands for about 10 seconds--at 50°F the motor will start at full voltage for 5 seconds than reduce voltage (and fan speed) to 50% of nominal voltage, as the sensor warms to 80°F the voltage will increase to 100% of nominal voltage.
